In this paper, establishing the level of‘syllable’on the segmental sequence, I will first examine the relationship between syllabic structure and vowel alternation. Then I will propose, presenting ample evidence, general rules of vowel tensing and vowel laxing, which have more explanatory power than any other rules that have ever been put forth. Finally, it will be shown that they are reducible to a single rule called Generalized Vowel Alternation Rule.
